F28035

Use of multiple timer in same code

Dear all,

I am working on F28035 controller. In F28035 we can select any one timer (0,1,2) as control clk source (default Timer2 is selected). This initializes that timer for all the operations(interrupt handling etc) in the code to run on this timer only.

If i want to initialize another timer & put some function's working on interrupt of this new timer which will have different frequency than primary timer then what settings need to be done?

Is it possible for us to control the flow of execution of code?

Can I use an isolated controlCARD with an experimenter kit?

Hi, I am planning to test F28035 with TI experimenter kit, Really appreciate if VisSIm engineer can help to confirm the following hardware assumption

  1. Either the no isolated or the Isolated F28035 controlCARD can be used on the docking station directly.
  2. If the Isolated controlCARD is used, I need to communicate through the JTAG on the controlCARD, but still need to power the +5V on the docking station
  3. If the no isolated controlCARD is used, I just need to connect the docking station with USB cable.

Thanks,
Alex

How can I get the C compiler for VisSim and TI F28035?

Is the C compiler provided by Visual Solutions or do I need to get the compiler separately?

What do you recommend for a good motor development platform?

I have had good success using VisSim with F2801 and F28027 but I want to design an ultimate motor control board for code development purposes. I like the TI320F28335 (the 150Mhz, 520KB Flash) DSP. Do you have any experience with this DSP? Is this the top of the line DSP that I can rely on? Will it work with VisSim? How easy it is to transfer 28335 code to a 2806 code? Does VisSim handle things differently for 28335?

If you think 28335 is not a good choice from VisSim perspective than let me know which one is?

Does VisSim/ECD have all I need to compile and download to the target?

Hi. I want to buy VisSim/ECD. Can you confirm that for a development program using the TI 28335 DSP processor that the only tools I would need to purchase is the VisSim/Embedded Controls Developer? Is everything included that would be needed to develop the models, code generate, and flash into the DSP or are other software modules needed?

How do I flash my Piccolo (F28035)?

Can I flash directly from VisSim?

dc buck converter won't work. Help!

I'm using your dc-2buck-f2808-d diagram as a starting point to control my buck converter. I've taken the output voltage and wired it to ADCINB0 through a 1K resistor (I know it should be buffered but I want to do a quick test). I'm assuming that c0: is the reference? So if I set that to .5 my reference would be full scale input/2? 1.5V? But when I move the slider to a non zero value, the regulator goes from 0V to full on. What am I doing wrong?

Can you explain the F280x PWM module? It's somewhat overwhelming when you first look at it.

There are 2 inputs to the VisSim ePWM block and when you right click there are many many options. Are there any other blocks or items that go with or belong with the epwm module or is everything self contained. I'm trying to sync a few modules and play with timing.

I downloaded the 100+ pages of TI epwm reference (SPRU791F) so this will keep me busy. Any recommendations or tips regarding this module? Thanks

Amazingly Low Cost TI Kits for Embedded Development

I have to say that I am very pleased with Texas Instruments latest round of DSP and microprocessor development kits. They have done an amazing job of taking the cost out of sophisticated embedded development. At one time, the JTAG pod alone cost $1500, now it is included free with the kit. They have the latest TI C2000 parts: F28335 and F28035, real-time JTAG connection to the PC, high quality analog sensors, and a very good C compiler.
